This is a mount for a logitech C270 webcam that I'm using with my D-bot. To use, remove the weighted folding mount that comes with the C270 and attach this using a 3mm bolt. After I made this, I found that the camera was not as high as it needed to be, so I used a couple of spacers to raise it up. This is just a quick and dirty design to get the webcam mounted on my new D-bot.
